In our research we focused on the supply with natural gas. EU wishes to completely cut ties with Russia in the field of energy supply, so it is necessary to quickly find other sources of supply. Time window is quite small. Planned reduction in consumption is not enough. Beside transferring natural gas through pipelines, the supply of natural gas is possible with ships. But adequate facilities alongside sea with hinterland pipeline network are required. We found out that it is possible to use regional ports, certain facilities with LNG infrastructure accessible by ships, for import of natural gas for Slovenia. Slovenia with no extraction or production facilities, no warehouses, and a substantial demand for natural gas must find suitable location through which it can include supply with ships into its energy policy. We identified nearby locations with needed technological properties to dock LNG tankers with adequate hinterland pipeline network to allow transport of natural gas to Slovenia. We discovered that it is possible to include supply with LNG tankers into Slovenia's energy supply by using certain locations near Slovenia. Findings of this research are useful for presenting future possibilities of supply of natural gas with LNG tankers through regional ports, closest to Slovenia.
